Abstract

In order to solve the problem of excessive temperature rise of brake discs under high-speed emergency braking conditions, carbon ceramic is being used as a new type of composite material in the development of new brake discs. By conducting fluid-solid-thermal coupling simulation, this article uses a front head train model containing brake discs to simulate the temperature changes of carbon ceramic brake discs during the braking process, meanwhile obtaining the temperature changes of the surrounding environment and comparing with the simulation results of steel brake discs. At an initial braking speed of 400km/h, surfaces of carbon ceramic brake disc can reach a maximum temperature of 1098.56K in about 86.3s, and the surrounding ambient temperature can reach a maximum of 750K.
